In my personal opinion I think that human beings are combination of good and bad with many factors in hand. What I may think is bad can be good to others and what I think may be good could be horrible to others. In other cases something may be wrong morally. Something may be wrong because society says so. It’s a matter of opinion. Here are a few examples to justify my argument.
A child for instance can be brought up with a family that society sees as near perfect and still turn in the complete opposite direction in life going down a path of violence or bad decision making. Maybe they looked up to the wrong role model, got involved in social networks that left a negative influence or maybe their family life has dark secrets that nobody knows about or even joins a religious cult which causes them to rebel in inappropriate acts. Most of the time when this happens they tend to dwell the fact that they want to be opposite of what they were “suppose” to turn out to be. I don’t think this makes them bad because in some cases it can be “fixed”. This child could have common sense to do the right things in life but continually goes the wrong path. The complete opposite of that, there could be a child with a horrible childhood, poor, no family and decided that they want a better life. So what this child does is realize they don’t want the path of violence and failure, they want to better themselves. There are many cases that this happens so where the “good” child grew up to be bad leads to my next example which could be a chemical imbalance.
You can have an adult that has always done right or a child for that matter and one day just snaps. This could also be from a triggered childhood or even a chemical imbalance which can sometimes be corrected by therapy or sometimes even surgery. This neurological problem often goes un-noticed. There have been serial killers that lead a very driven “perfect” life but can’t control the inner demons that have overtaken
